Performance engines often have higher compression ratios and special cam timing. They also operate at higher RPM. In addition, they may be supercharged, turbocharged or use nitrous oxide. These conditions will increase the cylinder pressure and stress on the cylinder head gasket.

In addition to high combustion pressures, performance engines often have a large amount of cylinder head movement. Racing and street performance engines develop much higher horsepower than their passenger car counterparts. For example, a Chevrolet 350 (5.7L) V8 racing engine can develop between 600-1000 horsepower, compared to 180-385 horsepower for passenger car and light truck applications.

On top of that, peak torque may occur at 5600 RPM for a typical racing engine compared to 3500 RPM for the same engine in a passenger car. These factors combined create a brutally tough environment for the head gasket. FEL-PRO Performance Head Gaskets incorporate special features to accommodate these conditions.The key difference between regular FEL-PRO PermaTorque® head gaskets and FEL-PRO Performance PermaTorque® Head Gaskets is a wire ring combustion seal inserted inside the stainless steel armor of FEL-PRO Performance Head Gaskets. The wire ring design provides highly concentrated sealing around the combustion chamber.

The wire ring helps concentrate the sealing load around the combustion chamber. Because of the wire ring, the combustion seal is squeezed by the head and block with a force about three times as great as standard head gaskets with a conventional armor and no wire ring. In addition, these Performance Head Gaskets have armors of the highest quality stainless steel available, and can withstand combustion pressures ranging from 1500 to 3000 psi.

FEL-PRO Performance Head Gaskets use a rubber/fiber facing material reinforced with KEVLAR® fiber, laminated to a solid steel core to resist torque loss and seal fluids. Conformable anti-stick coatings are used on the gasket body to help seal minor surface irregularities.

Besides aiding in micro-sealing, anti-stick surface coatings make gasket removal and cleanup easier. This is a special advantage in performance applications, where engine changes and repairs require frequent disassembly.

Fel-Pro Performance Head Gaskets comes with Perma Torque Blue Stripe and pre-flattened wire rings in either steel or copper. price per each
